    I have a real loud raddling/knocking sound that was told was coming from Torque converter. So know im trying to figure out if theres any benefit at all going with a triple disc converter $495 or just a replacement oem $350 also heard of some 6.0 tc but not sure on prices yet. my truck has 300k...
